Forgive me if there is a thread buried on this site about installing a charging outlet in your garage. I have not done a thorough search, and I figured I would keep the conversation fresh and keep the threads coming as we wait, wait, and wait some more for Model X. In terms of price, what am I approximately looking at to install a proper charging outlet in my garage for my future Model X?? I have heard anywhere as low as $500-600, as well as upwards over $1,000. Also, is the charging outlet 220V?
